Tonimbuk is a bounded rural locality in Victoria, Australia, 70 kilometres (43 mi) south-east of Melbourne's Central Business District, located within the Shire of Cardinia local government area. Tonimbuk recorded a population of 208 at the 2016 Census.
Devastating fires in early March 2019 almost wiped this town off the map. It has since recovered and, like the state forests and farmlands that surround it, is now growing again.
A Telegraph Office was open at Tonimbuk from 1953 until 1959.
